BlockAllDynamic not working

[rtscts]

I’m new to unreal engine, the global setting is clean, and we i setup a test for collision(as follows),
setting the sphere to blockalldynamic, and the sphere goes through the wall(which should stop)

did I miss something here?

If you made a blueprint and put a sphere in it, and wrote some movement code, it will still go right through the wall. You also have to write the collision detection code.

Or, you could use physics, or inherit from ‘character’ or ‘pawn’.

Thanks for your reply. I do use physics in my blueprint, which is named Box in the blueprint(In the Components tag of the first image). It’s a Box collision.

collision detection

now i added the collision detection. The sphere still go through the wall

[ClockworkOcean]

Try overlap, rather than hit. But I think you might need a lot more code ( for walking up and down stairs, for instance ), which is why people inherit from pawn etc.

Make the basic collision shape the root component. Projectiles only register collisions on the upper most root element that is a collision primitive.

Thank you so much, It bother me a day

Try set both generate hit event as activate.
